Question

Ce adancime reala are apa dintr-un bazin, daca privind perpendicular pe suprafata apei ni se pare ca are o adancime de 2 m ?

Answer 1

[tex]\text{Adancimea aparenta este data de relatia:}\\ \boxed{d=h\cdot\dfrac{n_1}{n_2}} \text{Inlocuind se obtine:}\\ 2=h\cdot\dfrac{1}{\frac{4}{3}}\\ 2=h\cdot\dfrac{3}{4}\\ h=2\cdot \dfrac{4}{3}\\ h=2,66\ m [/tex]
